What model Yggdrasil do you have?

The original... not the + . It is out on loan because it isn't my kind of thing and it deserves to be used. It is a very good DAC.
I also have a Soekris 1021 R2R kit that I haven't had time to finish due to everything going on here.

The "original" was upgraded years ago, before the +, og, mil, lim. If your serial number begins with "A", there was significant upgrade to "B" serial number.
Also, what input do you use?

Well, since I build USB cables, that would be USB. Optical sucks, AES is a flawed method, SPDIF over RCA doesn't sound right and I don't have a source with BNC. My source is a modified MAC mini with a dB Audio Labs OS. If it had an HDMI input I would be interested in trying that, but my friend Greg would be sad to give it back. :lol:

@P.I.
EDIT: I see you recognize what I stated and have corrected your post as far as where to place your text.
I'm assuming this is your last post: (you encapsulated a series of quotes inside other quotes so your reply does not standout).

I figured you would be using USB, given the "hot rodded" (whatever that means you had done, likely upgraded caps) Tranquility DAC.
O.K. I was just curious. Not wanting/looking to debate or be argumentative. But the "A" serial number Yggy you bought if original (2015?) likely didn't even have the Gen 5 USB card. So today's OG Yggy (which would be serial number B had you upgraded the A, i.e. the analog board itself was upgraded) also contains their proprietary Unison USB, supposedly the greatest thing since sliced bread as far as USB is concerned. Or so claim the Schiit fan club and those who have used it, reviews, etc. I wouldn't know as I don't (no longer anyway) use USB.
To your statement that "AES is a flawed method", again, I prefer not to debate or be argumentative but suffice it to say I adamantly disagree and in fact believe it to be the **very best** of digital inputs one can use. Even better than I2S/HDMI, which by the way is not completely standardized.
I'd be interested in reading any citation you could post supporting your claim "AES is a flawed method". Prior to Unison USB, Mike Moffat himself claimed AES/EBU to be the best digital input, and not just for Yggy.
Optical too can be very good if done right so I personally wouldn't go as far as stating it "sucks". I use optical from my LG C9 to feed Yggy and it's entry level optical cable and still sounds grate. Glass optical is best (of optical) but who can use that from a practical perspective?
I use SPDIF RCA on my main transport Oppo UDP205 (99.9% of listening) only because it doesn't have AES output, and AES output from my ERC3 in the off chance I happen to listen to a CD (almost never).
Happy listening. :)
Best.

Speaking for myself, I can't reliably hear a difference between Redbook and hirez formats
with my current DAC, Auralic Vega. There are a lot of ways
D to A can wrong.
You can loose what differentiates Redbook
from hirez in the DAC itself or in the following analog gain stage.
I'm sure many more sources of degradation will occur to the members
of this site. I would like to believe that the differences between Redbook
and hirez sources is as large as that between CD at 1411kps and 320kps.
In my system this difference is audible but subtle. So far I have not been able
hear a difference of this magnitude between hirez and Redbook. I blame the
DAC I use but I kind of quit chasing perfection a few years ago and settled for
good enough. No regrets. :D

My thing is that I have about 3TB of Redbook files! I'd rather fight than switch! :rofl:
